ClpP1/2 heterocomplex from Listeria monocytogenesClpP1/2 heterocomplex from Listeria monocytogenes
Structural highlights
FunctionQ8Y7Y1_LISMO Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins (By similarity).[HAMAP-Rule:MF_00444] Publication Abstract from PubMedListeria monocytogenes is a devastating bacterial pathogen. Its virulence and intracellular stress tolerance are supported by caseinolytic protease P (ClpP), an enzyme that is conserved among bacteria. L. monocytogenes expresses two ClpP isoforms that are only distantly related by sequence and differ in catalysis, oligomerization, active-site composition, and N-terminal interaction sites for associated AAA(+) chaperones. The crystal structure of the ClpP1/2 heterocomplex from L. monocytogenes was solved, and in combination with biochemical studies, it provides insights into the mode of action. The results demonstrate that structural interlocking of LmClpP1 with LmClpP2 leads to the formation of a tetradecamer, aligns all 14 active sites, and enhances proteolytic activity. Furthermore, the catalytic center was identified as being responsible for the transient stability of ClpPs.
